  • The Abies koreana Wilson has been unique species of Korea and has not been clearly investigated about lignans of extractives. This studies have been carried out from the isolation and determination of lignans from alcoholic extractives in its xylem. Six lignans were isolated and their structures were determined by spectroscopic methods. They were two new compounds, (+)-koreslactol and (-)koreanol and four known compounds, lariciresinol p-coumarate, (+)-todolactol C, (-)-${\alpha}$-intermedianol, and (+)-pinoresinol.

  • 구상나무(Abies koreana Maximowicz)와 전나무(Abies holophylla Wilson) 잎을 채취하여 건조시킨 후 분말로 제조하여 각각 1.5 kg을 아세톤-물(7:3, v/v)로 추출하고 헥산, 메틸렌클로라이드, 에틸아세테이트 및 수용성으로 분획하여 동결건조 시켰다. 에틸아세테이트용성 분획을 Sephadex LH-20으로 충진한 칼럼에서 메탄올과 에탄올-헥산 혼합액을 용리용매로 사용하여 칼럼크로마토그래피를 실시하였다. 단리된 화합물들은 TLC로 확인한 후 $^1H-$, $^{13}C-NMR$, COSY, HETCOR 등의 스펙트럼을 사용하여 정확한 구조를 규명하였고 FAB 및 EI-MS로써 분자량을 측정하였다. 많은 양의 aromadendrin-7-O-${\beta}$-D-glucopyranoside (화합물 III), polydatin (화합물 VI), (-)-rhododendrol-2-O-${\beta}$-D-glucopyranoside (화합물 VII)가 단리되었으며, 소량의 (+)-catechin (화합물 I), kaempferol-3-O-${\beta}$-D-glucopyranoside (화합물IV), myricetin-3-O-${\beta}$-D-glucopyranoside (화합물 V), naringenin-7-O-${\beta}$-D-glucopyranoside (화합물 II)도 단리 되었다. DPPH 라디칼 소거법을 이용하여 단리된 화합물들에 대한 항산화 활성시험을 실시하였으며 (+)- catechin과 polydatin이 항산화 효능을 나타내었다.

  • To improve our understanding of the relationship between soil higher fungi (belonging to Ascomycota and Basidiomycota) and Abies koreana, we surveyed A. koreana soil fungal communities in a forest in Mt. Halla, Jeju Island, Korea by next-generation sequencing (Illumina Miseq). To confirm the soil higher fungal communities, we collected two types of soils from a defined plot: soils with dead (AKDTs) and living A. koreana (AKLTs), respectively. Soil fungi were classified into 2 phyla, 19 classes, 64 orders, 133 families, 195 genera, and 229 OTUs (895,705 sequence reads). Nonmetric multidimensional scaling (NMDS) showed significantly different soil higher fungal communities between AKDTs and AKLTs (p < .05). In addition, the saprophyte composition was significantly affected by A. koreana status (p < .05). The proportion of the mycorrhizal Clavulina spp. was different between soils with AKDTs and AKLTs, suggesting that Clavulina spp. may be a crucial soil fungal species influencing A. koreana. This study will lead to a better understanding of the ecological status of A. koreana in Mt. Halla. In addition, this study could be useful for the conservation and management of A. koreana habitats.

  • In this study, the roots and rhizosphere soil of Abies koreana and Taxus cuspidata were collected from sites at two different altitudes on Mt. Halla. Ectomycorrhizal fungi (EMF) were identified by Illumina MiSeq sequencing. The proportion of EMF from the roots was 89% in A. koreana and 69% in T. cuspidata. Among EMF in rhizosphere soils, the genus Russula was the most abundant in roots of A. koreana (p < 0.05). The altitude did not affect the biodiversity of EMF communities but influenced fungal community composition. However, the host plants had the most significant effect on EMF communities. The result of the EMF community analysis showed that even if the EMF were isolated from the same altitudes, the EMF communities differed according to the host plant. The community similarity index of EMF in the roots of A. koreana was higher than that of T. cuspidata (p < 0.05). The results show that both altitude and host plants influenced the structure of EMF communities. Conifers inhabiting harsh sub-alpine environments rely strongly on symbiotic relationships with EMF. A. koreana is an endangered species with a higher host specificity of EMF and climate change vulnerability than T. cuspidata. This study provides insights into the EMF communities, which are symbionts of A. koreana, and our critical findings may be used to restore A. koreana.

  • 지리산 국립공원의 천왕봉(1,915m)-덕평봉(1,521m)을 중심으로 한 고산지대에 분포하는 우리나라의 특산종인 구상나무의 생육현황과 구상나무림의 군집구조를 정확히 파악하여 앞으로의 구상나무림 관리의 기초자료로 활용하고자, 구상나무가 분포하는 지역에 48개의 조사구($10{\times}10m$)를 설치하여 식생을 조사하였다. Cluster 분석 결과 조사 대상지는 세 개의 집단 구상나무 군집, 구상나무-신갈나무 군집, 가문비나무-사스래나무 군집-으로 분류되었다. 수종간의 상관관계는 가운비나무와 마가목 ; 신갈나무와 쇠물푸례 및 노린재, 나래회나무와 산앵도나무 등의 수종들 간에는 비교적 높은 정의 상관관계들, 신갈나무와 마가목 등의 수종들 간에는 높은 부의 상관관계를 보였다. 본 조사지의 종다양도는 0.7208-1.2074로 나타났다. 구상나무의 활력이 저조한 것으로 나타났으며, 12.24%는 고사목이었다. 구상나무 고사목은 흉고직경 10-30cm 범위의 것들이 대부분이었다.

  • This examination of vegetation is conducted from lune to Oct. 1999 through on the spot survey, centering on the habitat of Abies koreana around Imgeolryeong, langteomok, and Jeseokbong in Mt Jiri and Yeongsil path and Seongpanak path in Mt. Halla. Species composition tables of the Abies koreana community by altitude and slope in Mt. Jiri and Mt. Halla are made based on the community composition tables examined in quadrat. The Abies koreana-Saso quelpaertensis community in a west slope of Mt. Halla is found that Abies koreana of 4-6m in height forms subtree layer and that of 8-9m in height the tree layer and it reflects a difference between community structure by slope and main composition species. While the tree layer of Abies koreana community is 12-14 in height around the area of 1, 290-1, 560m above the sea of Imgeolryong and path from Baekmudong to Jangteomok, it is 8-12m in height in the area of 1, 680-1, 780m above the sea of path from Jangteomok to Jeseokbong. It means that community structure depends on area and attitude. This study finds out that commonly appearing composition species similar to coverage and presence are Lepisorus thunberianus, Quercus mongolica, Soidago virga-aurea var. asiatica, Ligularia fischeri, Carex lanceolata, Clintonia udensis, Magnolia sieboldii, Betula ermani, Acer Pseudo-sieboldianum, As soil environment of surveyed area, pH of surveyed spots is similar in Mt. Jiri and Mt. Halla, electrical conductvity is higher in Mt Jiri, and contents of organic matter is relatively higher in a west slope of Mt. Jiri and Mt. Halla and lower in their south and west slopes. Contents of organic matter and total nitrogen show that the area of 1, 550m above the sea in a west slope of Mt. Halla is some higher. For pH and contents of total nitrogen and organic matter, Mt. Halla is higher than Mt. Jiri but for electrical conductivity , Mt. Jiri is relatively higher than Mt. Halla.

  • Racodium therryanum from Korea is described here for the first time. This fungus is characterized by that it is isolated from conifer seeds and seedlings, including Abies, colonies are dark green to dark gray and intricate, and it forms chlamydospores in cultures. This pathogenic fungus was isolated from seeds of Abies koreana growing on Mt. Halla, Jeju island. The fungus stopped growth more than at $30^{\circ}C$ but grew even at $O^{\circ}C$. This fungus infected seeds of A. koreana under the snow during winter season. There is a high probability that this fungus affects the natural regeneration of A. koreana on Mt. Halla.

  • We found an unrecorded endophytic fungus, Dermea piceina J.W. Groves, isolated from alpine conifer Abies koreana. Until now only one Dermea species, D. cerasi, has been reported in Korea. In this study, we compared morphological characteristics and DNA sequences, including internal transcribed spacer and 28S ribosomal DNA, of D. piceina isolated from A. koreana with those of related species. Here, we present morphological and molecular characters of this fungus for the first time in Korea.
